Re: LPAR on very small machines -- MIDRANGE-L

You can do partitions on a small machine - they'll just be very small partitions. The issue, IIRC, has more to do with the peripherals. You need duplicates of some devices, like CDs, you probably need an extra tower for various cards where you can attach external tape drives - not recommended on production machines, BTW, but I've hot-switched a 3490 between LPARs in the lab at IBM. It's no small task to retrofit a machine for LPARs.

Management of these things should not require HMC, except for some new stuff that I don't remember - I think a Linux or AIX partition without a primary is where this comes in. With a primary partition this is all manageable in DST, or to some degree in iSeries Navigator when you've added a service entry in WRKSRVTBLE (I forget details again).

I'm not sure how far back in releases you can go with a V5R3 primary - there is a restriction, I believe.

Even though the sales manual says a small 520
can support "more than one" logical partition,
is it really possible to do it on a small machine?

The HMC looks to be a "requirement" in the I5
series, but what would other boxes use instead of
that to control partitions ???

I have a customer that wants to keep a copy of
V4R5 in a partition and run V5R3 as the primary.
Is that even possible ???

Other than the concept, I know little if anything about
LPAR.
